WATIJR-FEED MECHANISM FOR [20F To all whom it may concern:

Be it known that I. lurnt'n llnxxnr, a citizen of the linited States, residing at llellevue, in the county of Huron and State f Ohio, have inventml certain new and useful improvements in 'ater-l eed Mechanism for Aeelylenelhis Generators; and 1 do declare the following to be a full. clear; and exact description of the invention, such as will enable others Skilled in ill. art to which it appertains to make and use the same.

This invention relates to improvements in acetylene generators and is a division from Patent 982902 dated Jan. 31, NJ 1.

The object of the invention is to provide a generator. in which the water is fed at predetermined intervals to the earbid chamber to provide for the generation of the gas to replace the amount utilized. 1

With this and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and claimed.

in the accompanying drawings: Figure 1 represents a vertical section through the gas bell and water tank and through a portion of the earbid receptacle; Fig' 2 is a detail front el vaiion partly in section on the line 2-9 of l and looking in the direction of the arrow; Fig. 3 is a detail fragmentary View showing the rotary water inlet valve. when in inoperative position; Fig. at is a similar view showing the valve in operative position.

In the embodiment illustrated, a carbid re; ceptacle 1 is shown of any preferred construction having a water feed pipe 2 entering through the bottom thereof. A water tank 3 is preferably arranged adjacent said carbid receptacle and is preferably in the form of a cylindrical casing havlng a gas hell 4 mounted therein. A cup 5 is arranged on the exterior of the tank 3 near its upper end, and the upper end of the Water feed pipe 2 extends through the bottom of said clip and is designed to feed water from the Water chamber at proper intervals to the carbid receptacle to cause the generation of gas as fast as it is utilized. The gas generated in said receptacle 1 preferably passes through a pipe 6 and a pipe 7 and into a Washer 8 and from the Washer passes into a gas pipe 9 which extends upwarlly and Specification of Letters Patent. Original application filed April 4, 1910. Serial No. 553.188.

delivers the gas into the gas hell 4 which rises and falls as the gas is generated and consumed. and may be held against rotary or axial di=plaeement by any suitable means.

llevolubl mounted in the tank 2; is a hotlow disk-shaped valve 10 having a hollow shaftll mounted iira bearing '12 and pro jet-ting into the cup 5.. This hollow valve is nori'nallv submerged in the water to above its hollow shaft and provided with an inlet opening l3 in its periphery which is above the water when the bell is raised and on its inner face is provided with a bifurfillttl memherdsl which is designed to receive apin or stud l5 projecting laterally from the outer face of the bell l. This valve 10 is held against retrograde movement by a pin lt' which extends from the periphery of said valve and is adapted to engage a stop 17 projecting from the inner face ol the receptacle 3.

A longitudinally disposed rib or angle iron 14' is secured to the outer face of the hell t in a plane slightly out of alinement. with the pin to and with its upper end termii'iating below said pin. This rib is designed tobe engaged by the free and of the HKll'llJGl '14 when the bell is in normal raised position, as shown in Figs. 2 and 3, to prevent; the valve being turned while the bell is in this position.

In the operation of the apparatus"; as the gas is consumed the hell 4- is lowered in the tank 3 and during its descent after the upper end of the rib 14 has passed below the member 14; the pin 15 engages the bifurcated member 14 and turns the valve 10 to bring the inlet opening 13 thereof into communication with the water in the tank 3, which permits the Water to flow thr llll the valve out of its hollow shaft into the cup 5 and from the cup 5 to pass through the feed pipe 2 to the cal-bid receptacle, and on coming in contact with the carbid in said receptacle causes the generation of more gas which passes ipto the bell 4 which is again raised thereby. The raising oft/he bell 4 causes the valve 10 to be rotated into the position shown in Fig. 3, and thereby cuts off the further supply of Water to the receptacle 1,.

the rib 14 member 14 ing.

The gas from the gasbcll 4 passes out through a pipe 18 to the service pipe (not being again engaged with said looks it agalnst downward turnshown). A pipe 19 communicating with the atmosphere extends upwardly through the tank 8 into a pipe 20 which depends from the top of the bell 4 and is provided with inlet ports 21 which are normally arranged below the water level of the tank 3. Should gas accumulate too rapidly in the hell 4; said bell will be raised a sntlicient distance to bring the inletv ports 21 above the water level and the surplus gas will flow out through said ports into the pipe 20 and pass into the upper end of the safety pipe 19 from which it passes to the atmosphere or to any suitable storage receptacle (not shown).

, From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without re- ,quiring'a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention claimed. 7

. I claim as my invention:

1. In an acetylene gas generator a water tank, a gas bell movable therein, a carbid-receptacle, a feed pipe discharging into the carbid receptacle, a hollow disk-shaped valve within the water tank provided with a concentrically projecting hollow shaft communicating with the interior of the valve and discharging into the feed tube, said hollow shaft being journaled in and projecting through the wall of the water tank a sufficientdistance below the top of the tank to submerge the'valve in the water therein to above the hollow shaft, the hollow disk having a peripheral opening, and means whereby the hollow disk valve will be rotated by the rise and fall of the bell to bringthe peripheral opening above or below the water when the bell is raised.

2. In an acetylene gas generator a water tank, a gas bell movable-therein, a carbid receptacle, :1 feed pipe discharging into the carbid receptacle, a hollow disk-shapedvalve within the water tank provided with a concentrically projecting hollow shaft communicating with the interior of the valve and discharging into the feed tube, said hollow shaft being journaled in and projecting through the wall of the water tank a sufiicient distance below the top of the tank to submerge the valve in the water therein to above the hollow shaft, the hollow disk having a peripheral opening, and means whereby the hollow disk valve will be rotated 'by the rise and fall ofthe bellto bring the peripheral opening above the water when the bell is raised and below the water level when the bell is lowered comprising a bifurcated bar secured to the disk with its points projecting radially-beyond" r the periphery thereof, and a pin carried by the bell and adapted to engage between the arms of the bifurcated bar as the bell rises and falls.

3. In an acetylene gas generator a water tank, a gas bell movable therein, a carbid receptacle, a feed pipe discharging into the cal-bid receptacle, a hollow disk-shaped valve within the water tank provided with a concentrically projecting hollow shaft communicating with the interior of the valve and discharging into the feed tube, said hollow shaft being journaled in and projecting through the wall of the water tank a s ufiieient distance below the top of the tank to submerge the valve in the water therein to above the hollow shaft, the hollow disk having a peripheral opening, a bifurcated bar secured to the disk and projecting radially beyond the periphery thereof, a pin carried by the bell to engage between the arms of the bifurcated bar as the bell rises, and falls,

a stop to preventover movement of thevalve as the bell rises, and a bar attached tothe bell out of vertical alinement with and below the pin to hold the valve against retrograde movement when the bell is raised.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
